Two cases of serous carcinoma of the ovary with squamous differentiation are described. These neoplasms occurred in two women who were 63 and 46 years old and who presented with International Federation of Gynecology and Obstetrics (FIGO) stage IIB and III disease, respectively. The first tumor recurred following chemotherapy; radiotherapy was given, but the patient died of tumor at 4 years. The second neoplasm did not respond to chemotherapy and caused the patient's death at 2 years. In the first case, the squamous differentiation occurred as compact nests of ovoid to spindle cells intermixed with a papillary serous carcinoma component. The squamous component of the second case developed as single or small groups of enlarged, eosinophilic cells, often multinucleated, within nests of papillary serous carcinoma with typical psammoma bodies. In the latter case, intercellular bridges were identified by light microscopy. Both cases showed squamous features by immunohistochemistry, staining positively for 57-kd keratin, although in the first case but not the second there was also some weaker staining for 54-kd keratin, probably indicating incomplete squamous differentiation with retained glandular features. Electron microscopy in both cases revealed prominent cytoplasmic tonofilaments in the squamous component. These two cases reinforce the concept that squamous differentiation, although more frequent in some other types of common epithelial tumors, may occur in serous ovarian carcinomas as well.
